This invention relates to the technical field, specifically to a drilling fluid control system for fractured formations. The system includes a pressure difference extraction module, a flow velocity deviation extraction module, a fracture abrupt change identification module, a channel switching execution module, and a pump pressure adjustment execution module. In this invention, by analyzing the fluctuation amplitude of the pressure time series difference between different depths in the wellbore and comparing the flow velocity change trend, a joint identification mechanism for abnormal seepage path changes is established. This triggers control commands to drive adjustments to the delivery channel state, shortening the response cycle from identification to execution and improving the flexibility of path control. Furthermore, after the channel state switching is completed, pump pressure adjustment is performed based on the resistance characteristics of the current connection structure. By dynamically adapting the delivery frequency and pressure output, the matching and control of the fluid operating state are achieved, enhancing the drilling fluid's adaptability to fracture abrupt change environments, mitigating pressure disturbances caused by abnormal seepage, and maintaining a stable wellbore operating environment.
